Then I tried to download from archive.org all 222 files linked from the main page; and successfully acquired 188 of them.

Only then did one of my attempts to reach the original site succeed. So then I tried to download the 34 files which were not found on archive.org; but unfortunately, the apparent reason that archive.org doesn't have them is that bd-fans.com also doesn't have them! I did a spot-check on a file or two which were on archive.org, and they were also present on bd-fans.com.

The 34 that I failed to download were as follows. (Note: some of these are of only tiny historical interest, like builds for OS/2 and PocketPC; and some others are readily acquired elsewhere, including artsoft.org; yet finally, there also appear to be a couple dozen which might be unique and therefore currently 'lost'. I marked with '(*)' some items below which I'm pretty sure are in 'standard' locations like artsoft.org or even, indeed, in the basic RnD downloadable packages). See the archive.org and/or bd-fans.com pages for readable descriptions:

I've attached the file your are looking for; it comes from an old (2012) dump of "www.bd-fans.com".

Maybe I should set up a mirror site for it on artsoft.org... My latest dump is from 2015, which has quite some additions compared to the 2012 dump, but which also already has all those missing files filbo listed above. :-/

-- did not understand from your comments about 2012 and 2015 dumps whether you might have any of these, or they remain lost. (And I do realize that the 2 tutorials + Contributions_2005 are well captured elsewhere, just not in the precise forms 'lost' from bd-fans.com...)
